摘要：
The invention relates to novel 2-nitro-4- or -5-pyridyloxyphenylphosphonic acid derivatives of the formula ##STR1## wherein X is halogen or trifluoromethyl, Y is hydrogen or halogen, one of the two substituents A and E is a phosphonate group ##STR2## wherein R is C.sub.1 -C.sub.4 alkyl or hydrogen, and the other is a nitro group, including the metal salts thereof and the salts thereof with ammonium and organic nitrogen bases, and to the preparation and use thereof. These compounds may be used for controlling weeds, regulating plant growth, or as microbicides.
